This shallow baseportion 7 is in direct communication with the body por- 'tion'fi and ispurposely instituted to pronlote spreading "of the sugar in anextensive"- layer over the heated bottom of the receptael'e 5, and itspassage as -a rather fine film, to the radially disposed jet outlets 8in a vertical peripheral flange indicated at 9.

vbotton'i consists of two sepaiable-rnetallic plates 10 and 11', thelatter of Whi h, as'best hoWn in Fig. IV is spirally groovedsothat'electric heating coils 12 and 1'3 of corresponding configurationmay be accommodated substantially in the plane of juncture or abutmentof the plates; The bottom of the'receptacle thus serves as a 'uefi'edthrough contact, enroute to the jet :outlets, and in Whichthe coils arecompletely "embedded for'protection and as a precau- "tion against tirehazard. Assemblage ofthe o f niovabie parts li-k ely "to tease toeeservers when thejmacomponent :parts of the receptacle structure'i'sm'aintained through the rnediuin of-cap screws I4: which passthrough the flanking port-ion 7 and take hold in'the pl-ate IO. Elieheating hnits or coils '12, 13 are {prefen ablyo-f the type in whichfthe'resistance ire is Wholly. surrounded byji nsulati'on encased of vheating element whereby the sugar is 'l'iqin a metallic sheathing, andit is to be especially noted that the convolutions of the spirals arerespectively mutually interspersed or nested and in close proximity forgreater compactness and heat concentration. The nesting of the coils, aswill be apparent from Fig. IV, in turn promotes uniform heatdistribution even though the coils are used separately as will behereinafter explained in detail.

The receiver 2, as best shown in Fig. II is generally bowl shaped withan annular troughed channel 15 surrounding a central opening 16 throughwhich the receptacle 1 protrudes. The top edge of the inner wall of thechannel of the receiver is overhung by a marginal extension 17 of thebottom plate 10 of the receptacle so as to preclude the possibility ofentry of the sugar floss into the opening 16. In order that it may bereadily removed for cleaning, the receiver 2 is not secured to the basebut merely rests upon a number of radially disposed cleats 18 which areconcaved in conformity with the cross section of the channel 15 andtherefore function to hold said receiver against displacement relativeto the spinning element 1.

The spinning element aforesaid, see Fig. [I, is mounted upon a spindle20 to which it is secured, a set screw 21 being provided in thedepending hub of the bottom plate 11, assistance being also lent by anut 22 threaded upon the reduced upper end of the spindle and bearingdirectly upon the companion bottom plate 10. Also secured to the spindleis a disk 23 disposed in spaced relation to the receptacle bottom byvirtue of the abutment of its hub against that of the bottom plate 11.To the bottom of the disk 23, are attached, with interposition of a diskof insulation 24, a number of contact rings, in the instance shown,three in number indicated respectively by the characters 25, 26 and 27.To the inner ring 27 are connected, through the medium of leads 28, 29,the inner terminals 30 and 31 of the heating coils 12 and 13respectively, while the outer terminal 32 of the coil 12 is similarlyconnected to the ring 25 and the outer terminal 33 of the coil 13 to thering 26. Ourrent is conducted to the contact rings 25, 26, 27 by brushes34, 35, 36 respectively, said brushes being guided in suitable holders37, mounted in the top of the base and urged against the rings byhelical compressure springs 38 concealed in the bottoms of the holders.The spindle 20 is rotatively supported by a bearing 39 mounted in orforming a part of a plate 40 secured upon the top of the base 4 andcovering an opening 41 therein. Said spindle 20 furthermore extendstot-he interior of the base and receives additional support in ananti-friction thrust bearing 42. A grooved pulley 43 secured upon theportion of the spindle within the base 4 intermediate the bearings 39and 42 receives motion by virtue of a belt connection 44. with thedriving motor 3, which, as previously stated, is mounted upon the top ofthe base 4 adjacent the receiver 2 and over an opening through which itsshaft extends.

In order that differ ,n't degrees of heat may be selectively maintainedduring the spinning operation, I have. instituted the provisions aboutto be described. To this end, the coils employed are of differentcapacities and subject to the control of a switch 45 of aconventionaltype, shown in elevation in Fig. I and diagrammatically in Fig. III, andcapable, through successive shiftings of its operating knob 46, ofconnecting the coils individually or collectively with the source ofelectrical energy, the power leads-of the circuit, in the latter of thetwo figures referred to, being indicated by the numerals 47 and 48. Theleads 47, 48 are connected through interposed fuses 49 and conductors5051 with the switch terminals 52-53. The latter 53 of these terminalstogether with the remaining terminals 54, 55 are in turn respectivelyconnected by conductors 56, 57 and 58 with the brushes 35, 36 and 34hereinbefore described as contacting with the rings 26, 27 and 2:") withwhich the terminals of the heating coils 12 and 13 are in circuit. Inthis connection, a pilot lamp 59 may be employed as an indicator ofcurrent flow, said lamp being supplied by conductors 60, 61 lead ingfrom the contacts 5354 of the control switch 45. Current for the motor 3is conducted from the line leads 47, 48 through fuses 62 and conductors63, 64 a control switch being interposed at 65, see Figs. I and III.

In operation, the switch 45 is first thrown to connect both coils 12, 13for quick heat ing, the motor then started to effect rotation of thespinning element 1, and the sugar (preferably of the granulated variety)is poured into the opening of the receptacle 5. liquefied throughheating, and, discharged as floss into the receiving bowl from which thefinished product may be-readil removed manually or otherwise as iteumulatesi After the receptacle bottom has become thoroughly heated, oneor the other of the heating coils 1213 may be cut out by propermanipulation of the control switch 45 as may be found necessary or'desirable in continued operation for proper production of the candy floss,thereby permitting practice of economy in current con sumptio-n. It isof course obvious that in lieu of two coils as many more may be employedas required in machines of difl'erent types or capacities. The embeddingof the heating Coils o andv consequent of avoidance of direct contactwith the mat-erial being fused, prevents scorching or burning, therebyenhancing uniformity of the product, and, what is of equal importance,entirely eliminating the fire hazard. Enclosing of the drivingconnections Within the base 4: not only serves to protect them butprevents possible injury to observers When the machine is used fordisplay or advertising purposes.
